We ALL knew what was going on. I was the lead engineer in our data center. I installed everything and oversaw all changes to our environment: HVAC, electrical, network, servers, everything. The fact that I was not permitted to install that hardware and it was installed by a bunch of guys in blue overalls freaked us out.
I don’t work there anymore, but I’ve heard from others who are still there who’ve said that more equipment is installed monthly. Not on the order of large SAN enclosures, but switches, servers, etc. I have no doubt it’s government stuff.
That is spooky.
